A New Jersey man has somehow survived ingesting 30 bags of heroin - or so he claims - while being chased down by police following an attempted robbery.

Michael Pelissier, 42, is accused of breaking into the Petco store on Route 17 north around 2.30am Tuesday.

Officers saw a suspicious 2004 Dodge Ram pickup pull out from behind the store and say Pelissier and another man, Robert Kwiatkowski, 52, were inside.

A plate check on the truck showed its plates were bogus and it had been stolen one week prior, according to NJ.com.

When cops flickered their sirens at the vehicle, the pair quickly pulled over and started running.

Police caught both of them after a brief chase.

As they were arresting Pelissier, he told police he had just swallowed 30 bags of heroin.
